Santa Cruz, CAWhere are you located?
Backlash is, as expected, ~0.0005". I have no problems holding dimensions within a thou across hundreds of parts.What kind of hours and backlash do your machines have?
One of my concerns, with the Torus Pro, is it is highly customized. It was always my primary machine. I immediatey ditched Mach3, and replaced it with my own CNC controller app, running over a KFlop. I ripped out and replaced the entire oiling system with a pressure-fed system that tailors oil deliverry to each individual way, and each ballnut. Of course, it has my PDB, and my 12-tool ATC, which, given it never went into production, I cannot provide any support for. So, to me, I either have to sell it as a "kit" that needs to be converted back to some standard cconfiguration by a more than usually knowledgable buyer, or spend the time to convert it myself, and sell it as a more-or-less stock machine, Of course, I do have a HUGE supplu of tooling, including probably 50 TTS tool holders of various shapes and sizes (several difference sizes of set-screw holders, dozens of ER20 and ER32 holders, 6 home-built tension/compression tapping heads, Tapmatic and Procunier tapping heads, numerous face mills up to a 5" Glacern with six inserts, several slitting saws, probably 5 or 6 vises in different sizes, including a 6" Glacern, three 4 or 5" lathe chucks, and more.
The Pulsar is actually a pre-production machine, with a few minor differences from the final production version, and I don't even recall what those differenecs are, other than slightly shorter travels. It is currently running with a SmoothStepper and UCCNC.
And spare spindles for both machines.
I have not used either machine in probably 3 years. Don't think I've even powered them on!
